SL(2,3) in SL(2,5)

Jump to: navigation, search
This article is about a particular subgroup in a group, up to equivalence of subgroups (i.e., an isomorphism of groups that induces the corresponding isomorphism of subgroups). The subgroup is (up to isomorphism) special linear group:SL(2,3) and the group is (up to isomorphism) special linear group:SL(2,5) (see subgroup structure of special linear group:SL(2,5)).

Definition

The group G is taken as special linear group:SL(2,5): the special linear group of degree two over field:F5.

The subgroup H is taken as a representative of the unique conjugacy class of subgroups of order 24. (The conjugacy class contains 5 subgroups).

This subgroup can be obtained explicitly using the quaternionic representation of special linear group:SL(2,3) over field:F5 (see also linear representation theory of special linear group:SL(2,3)).
